What are the main physical properties of silver?

Pure silver is nearly white, lustrous, soft, very ductile, malleable, it is an excellent conductor of heat and electricity. It is not a chemically active metal, but it is attacked by nitric acid (forming the nitrate) and by hot concentrated sulfuric acid.

Both have gray undertones, unlike white gold which has a warmer, yellow undertone, but platinum is much brighter and shinier and silver has a duller, gray appearance.

What is a chemical property of silver?

It has the highest electrical conductivity of all metals, but it is not widely used for electrical purposes as it is very expensive.

What is the difference between silver and platinum?

Silver and platinum both have gray undertones, unlike white gold which has a warmer, yellow undertone, but platinum is much brighter and shinier and silver has a duller, gray appearance. The difference in durability is really no contest between platinum, white gold and silver.
